Scott Baio and siblings put their mother's Toluca Lake home on the market

Actor Scott Baio, his brother Steven and his sister Stephanie have listed the Toluca Lake home where their mother lives at $4,995,000.

The 11,000-square-foot house, a guesthouse and a swimming pool sit on more than a half-acre of gated grounds. The master suite includes a sitting room, a fireplace, a separate gym and an office. There are seven bedrooms and eight bathrooms total, plus a 10-car garage.

The late Mario Baio had purchased the property in 1994 for $1,305,000, public records show. His children said they are selling because the house is too large for their mother, Rose.

After roles in the sitcoms "Happy Days" (1977-84), "Joanie Loves Chachi" (1982-83) and "Charles in Charge" (1984-90), Baio gained a new generation of fans playing lawyer Bob Loblaw on "Arrested Development" (2005) and himself in "Scott Baio Is 45 … and Single" (2007).

Steven Baio acted on "Happy Days" (1983-84) and "Joanie Loves Chachi" (1982), among other programs. Steven's twin, Stephanie Baio, is director of operations at the House Ear Clinic in Los Angeles.

Scott Sorrentino and Lisa Sorrentino of Rodeo Realty are the listing agents.
